Authorities on Tuesday were still trying to find eight of 11 people who passed through an unattended security checkpoint lane at John F. Kennedy International Airport.
The travelers managed to breach security at Terminal 5 Monday morning, according to PANYNJ spokesman Joe Pentangelo.
Pentangelo said authorities identified three of the travelers, who got onto a flight to California and were expected to be screened upon arrival there. The eight other people are believed to have boarded various flights.
The TSA confirmed that three passengers weren't properly screened after they walked through a metal detector, setting off alarms. The agency said all personal carry-on bags received the required screening.
It took the TSA two hours to report the breach to police.
The agency said it's reviewing the incident, but that a K9 team was present at the checkpoint at the time and that the "incident presents minimal risk to the aviation transportation system."
